PROBLEM TO BE SOLVED: To provide a press device capable of shortening an index time with a simple constitution, improving a processing capacity, and preventing an excessive pushing pressure applied to a part (IC device), and an IC handler and an IC handler inspection device. SOLUTION: This press device has an air cylinder 13 driven by an air pressure, for pressing the IC device, an electropneumatic regulator 35 for supplying the air cylinder 13 with air, and controlling the pressure applied to the air cylinder 13, and an electromagnetic three-way valve 37 installed between the electropneumatic regulator 35 and the air cylinder 13, for supplying the air cylinder 13 with the air from the electropneumatic regulator 35. The IC device is brought into contact with an inspection socket 41 in the state where the inside of the air cylinder 13 is decompressed, and when pressing the IC device, the electromagnetic three-way valve 37 is opened and the inside of the air cylinder 13 is pressurized up to a prescribed pressure for pressing the IC device with the optimum load.
